NexGard PLUS chews are a once monthly, delicious beef-flavored chew that provides protection against fleas, ticks, heartworm disease, roundworms and hookworms. Keep up with monthly dosage to ensure year-round protection. See product label for full details and directions for use.

NexGard PLUS chews protect against fleas and ticks, prevents heartworm disease, and treats and control roundworms and hookworms.

NexGard PLUS chews contain 3 active ingredients: afoxolaner kills fleas and ticks, moxidectin prevents heartworm disease, and pyrantel treats and controls roundworms and hookworms.

One of the active ingredients in NexGard PLUS chews (afoxolaner) absorbs into the system within 6 hours. In a controlled study, they were found to be 99% effective on pre-existing flea infestations, killing them within 8 hours, and newly acquired fleas are killed within 24 hours. NexGard PLUS chews kill black-legged ticks within 48 hours.

NexGard PLUS chews provide powerful protection against fleas and ticks for a full month. Each monthly chew works to prevent heartworm disease by killing any heartworm larvae that were acquired in the previous month. It’s important to ensure that your dog receives a monthly NexGard PLUS chew year-round to keep your dog protected against fleas, ticks, and heartworm disease.

You can tell NexGard PLUS chews are working by looking for dead fleas and ticks, and by noting if your dog’s scratching decreases.

NexGard® (afoxolaner) chews and NexGard PLUS chews are manufactured by Boehringer Ingelheim. 

Use NexGard chews with caution in dogs with a history of seizures or neurologic disorders. For more information, click here for full prescribing information.

Your dog will need an annual negative heartworm test and a prescription for NexGard PLUS chews from your veterinarian.

In a well-controlled laboratory study, afoxolaner alone began to kill fleas within 4 hours and demonstrated >99% effectiveness at 8 hours.

NexGard PLUS chews contains afoxolaner. Once administered, it is absorbed into the bloodstream. When fleas and ticks ingest blood containing afoxolaner, it causes hyperexcitation and kills the parasite.

NexGard PLUS chews effectively kill existing fleas and prevents future infestations by killing fleas before they lay eggs. However, if you have an existing flea infestation before starting your dog on a flea control product, additional steps may be needed to help remove developing flea stages (eggs, larvae, and pupae) from your home, which can continue to hatch and cause an infestation for months.

You are likely seeing NEW fleas on your pet, which are jumping on your dog as they move through infested areas. These fleas will be killed quickly by NexGard PLUS chews before they can reproduce. Depending on the severity of an already existing infestation as well as environmental conditions, you may continue to see new fleas jumping on your pet for 3 months or more. To prevent new infestations, continue to give NexGard PLUS chews consistently each month throughout the year.

Fleas can cause itchy, painful skin conditions on your dog. Signs of fleas include scratching or biting at the skin, hair loss, scabs, and irritation.

If fleas go untreated, they can quickly multiply to cause an infestation. A single adult female flea can lay up to 50 eggs per day, which means that a small number of fleas can grow into the thousands.¹ An infested dog will scatter flea eggs throughout their home environment, and fleas will bite other animals, including humans.

In well-controlled laboratory studies, afoxolaner alone demonstrated >97% effectiveness against Dermacentor variabilis (American dog tick), >94% effectiveness against Ixodes scapularis (black-legged tick), and >93% effectiveness against Rhipicephalus sanguineus (brown dog tick) 48 hours post-infestation for 1 month.

NexGard PLUS chews do not prevent ticks from getting on your dog or the ticks from attaching. They do, however, kill them rapidly within 48 hours of attachment.

Ticks can be hard to spot on dogs. Since they bite the skin, underneath your dog’s fur, it can be difficult to locate them. They also may bite hard-to-reach areas, such as under the neck or beneath the armpits. Your dog may scratch at or gnaw on tick bite locations. Ticks can also transmit various life-threatening tick-borne illnesses.

Yes. Ticks are carriers for several dangerous diseases. If a tick that is carrying a pathogen bites a dog, that dog is at risk of becoming infected as well.

NexGard PLUS chews have moxidectin in it, which prevents heartworm disease before they mature into adults. It also has pyrantel, which treats and controls roundworms and hookworms.

Yes. NexGard PLUS chews prevent heartworm disease by killing heartworm larvae before they mature into adults. NexGard PLUS chews are also effective at killing fleas, ticks and controlling hookworms and roundworms with convenient monthly one-and-done protection.

Heartworm disease is a serious and potentially fatal disease in dogs and cats. It is transmitted to pets via mosquitoes, and even a single bite of infected mosquito poses risk of heartworm disease. Adult heartworms live in blood vessels of lungs, and in severe cases heart, causing irreversible damage.¹

Dogs get heartworms from infected mosquitoes. Heartworm larvae enter the dog through the mosquito bite and over time develop into adult heartworms, which cause heartworm disease. One bite is all it takes.²

There are 3 things you can do to help reduce the risk of heartworm disease:

1. Use heartworm disease preventives, like monthly NexGard PLUS chews, on a year-round basis to prevent heartworm larvae from growing into dangerous adult heartworms.⁴
2. Reduce mosquito exposure by eliminating standing water where mosquitoes can breed, avoid known mosquito habitats, and limit outdoor exposure during peak mosquito feeding times.²
3. Get your dog tested every year. Before getting a prescription for a heartworm disease preventive, your dog should be tested for heartworms. Talk to your vet about testing options.²

Because heartworm disease is passed on from the bite of an infected mosquito, there is no natural prevention for your pet. Talk to your veterinarian about the different heartworm disease preventive medications available for your pet.

Yes, it can be treated, but heartworm disease is a serious condition that can cause heart failure, permanent damage to your pet’s lungs, and even death.⁴ Treating heartworm disease is costly and complicated.⁵
